Gutsman, based on the Megaman video game

"The attack was sudden and destructive, our MOBAT tanks and Armadillos being tossed about like tin cans. That's when we saw what was doing the damage. It was a single soldier calling himself 'Gutsman'. After a long battle Rock and Protoman were able to drive him into a retreat. We later learned that Zartan had stolen our plans so that Cobra could create dimensional gateways too. Beings known as Repliods were joining their side under control of a mad doctor that Cobra Commander had formed an alliance with...some fellow named Wily."
